The couple, who looked loved-up as they watched England beat Wales in the Six Nations, will reportedly get engaged within weeks, the Daily Star reported.

Royal
sources believe that the pair would tie the knot at Westminster Abbey on September 27, just 12 days after the prince turns 30.

The duo also recently indulged in rare PDA at a charity event at the Wembley Arena.

The 24-year-old blonde beauty was seen planting a kiss and hugging her royal boyfriend when he returned to his seat after giving a speech in front of over 12,000 students in Wembley, the Daily Star reported.

The couple is also enjoying a lot of popularity which was proved when they came before the Duke and Duchess of Cambridge, Prince William and Kate, as party guests that people would most like to invite in a recent list.

The raving regal couple topped a list of famous faces that people wanted on their party guest lists, compiled by Tatler magazine.

Cressida and her redheaded royal boyfriend even managed to top One Direction star Harry Styles on the list.
